SUCTION GAS-PRODUCER APPARATUS.

Specification of Letters Patent.

Patented Dec. 1, an.

Application filed July 2, 1914. SerialNo. 848,661.

from the fuel and the utilization of the combustion of the hydrocarbon vapors for the generation of steam. (b) The formation of coke for the production of producer gas freeof hydrocarbon vapors for use for various purposes. supplying of steam for use in the gas producer and for auxiliary purposes while gas is being generated. (cl) The prevention of adhesion of clinker and slag to the producer walls. (6) The use of the producer as an ordinary steam generator for the supply of steam when gas is not required.

The invention will be considered as if it were applied to gas producing plant installed on a ship or vessel. With gas producers employed for marine purposes, it is necessary that the producers should generate gas free from hydrocarbon vapors. It is also necessary that steam should be generated and supplied to the producer for the enrichment of the gas by hydrogen. Steam also is required in a vessel or ship for a varietyof auxiliary purposes such as heating, cooking and driving of auxiliary machinery, winches and other apparatus.

The invention will nowbe described with reference to the accompanying drawing in wh1ch Figure 1 is an elevation of a suction-gasproducer constructed according to this invention, and Fig. 2 is a vertical section of Y tically forming an upper chamber 0 where the coking of the coal or other fuel takes place. In the top portion of the upper chamber is a combustion space or chamber 0, from the crown e of which tubes f may pass vertically through the Water and steam (c) The generation and space 9 to the smoke box it and Smokestack it in a similar manner to that found in known steam vertical boilers. The fuel for the furnace may be fed through a fire door 11 placed in the vicinity of the combustion space. Air is admitted through a conduit. or belt j and one or more rings of tubes or. nozzles Z2 placed preferably just below the working level Z of the fuel when the plant is being used for the-production of gas and generation of steam. Additional airas may be required for the combustion of the hydrocarbon vapors and other gases can'be supplied through regulating shutters m on the furnace doors 2' or in other suitable ways.

The top ofthelower or producer furnace at is preferably conical in shape as at a, while a skirt plate cl suspended within the conical portion forms with the latter an annular space a from which the gas can be drawn by means of'tubes a passing through the waterjacket I) intoa gas bell or receiver 0.

'The gas-producer boiler may be mounted on a metal or other base 79 which can be provided with a removable step fire grate 57 and with doors '7 provided for the removal of ashes, etc.

Air for the producer is admitted through a suitable inlet or inlets s in the base, by means of pipe u, the supply being controlled by a slide a or other suitable device. Steam can be admitted by means of pipe 4), in

valved communication with the steam space gand discharging into pipe a. Pipe 0) is fitted with a regulating valve or cool: 1).

Suitable baffle plates or other means, not

shown, are provided inthe gas belt near the outlet so as to insure even suction over the area of the fire. Poking holes t to the lower furnace or gas producing portion a shouldbe provided through a number of the tubes at in the gas belt; similarprovision for poking is made through the airtubes Z" to the upper furnace 0. The apparatus is provided with cleaning holes, mansholes and usual boiler mountings. v

The coal or other fuel is fed through the furnace door 2' and is roasted or coked, the hydrocarbon vapors being driven off and burned in the combustion chamber on mixing with the air introduced. The flames of these gases pass through the tubes f to the smoke 'box It generating steam in the surrounding water. The fuel as coke free from hydrocarbons, reaches the lower furnace a where gas is formed by the air and steam being drawn through the fire.

The quantity of steam generated by the combustion of the hydrocarbon vapors, with water jacketing to the producer furnace.

iirevents the adhesion of the clinker to the sides of the walls of same.

By fitting an induced draft to the uptakes from the boiler portion of the producer, the whole of the producer can be drawn up to a state of gas making in readiness for the supply of gas to the main engines. By lowering the fuel level to a position comparatively close to the top of the grate q for instance to the level Z, the appaatus may be usedv simply as a boiler for supplying steam, which, in the case of a vessel in port for loading or discharging purposes, can be utilized in working winches and other apparatus.

The gas producer boiler may alternatively be arranged with either horizontal or inclined smoke tubes, return smoke tubes, vertical, horizontal or inclined water-tubes, or tubes of the Galloway type placed in the upper furnace.

Having now described the nature of my said invention and the best means I know of carrying the same into practical eifect, I claim 1. A combined suction gas producer and steam boiler apparatus comprising a producer furnace, a coking chamber embodying a combustion space, said chamber arranged in superposition in respect to and in open communication with the furnace, a second or outer chamber inclosing the furnace and the coking chamber and having a water and a steam space, a smoke box disposed above the said outer chamber and communicating with a flue or uptake, a series of tubes communicating with the combustion space of the coking chamber and the smokeiboii, means for drawing off gas from the producer furnace, means for admitting steam from the steam space in the outer chamber to the furnace, means for admitting air to the furnace and means for admitting air to the coking chamber.

2.. A combined suction gas producer and steam boiler apparatus comprising a producer furnace, a coking chamber embodying a combustion space, said chamber arranged in superposition in respect to and in open communication with the furnace, a second the said outer chamber and communicating with a flue or uptake, a series of tubes communicating with the combustion space of the coking chamber and the smoke box, means for drawing off gas from the producer furnace, adjustable means for admitting steam from the steam space in the outer chamber and air to the furnace, and means for admitting air to the coking chamber.

3. A combined suction gas producer and steam boiler apparatus comprising a producer furnace, a coking chamber embodying a combustion space, said chamber arranged in superposition in respect to and in open communication with the furnace, a second or outer chamber inclosing the furnace and the coking chamber and having a water and asteam space, a smoke box disposed above the said outer chamber and communicating with a flue or uptake, a series of tubes communicating with the combustion space of the coking chamber and the smoke box, means for drawing off gas from the pro ducer furnace, means for admitting steam from the steam space in the outer chamber and air to the furnace, means for admitting air to the coking chamber, and adjustable means for admitting air to the said combustion space.

4. A combined suction gas producer and steam boiler apparatus comprising a producer furnace, a coking chamber embodying a combustion space, said chamber arranged in superposition in respect to and in open communication with the furnace, a second or outer chamber inclosing the furnace and the coking chamber and having a water and a steam space, a smoke box disposed above the said outer chamber and communicating with a flue or uptake, a series of tubes communicating with the combustion space of the coking chamber and the smoke box, means for drawing off gas from the producer furnace, adjustable means for admitting steam from the steam space in the outer chamber and air tothe furnace, means for admitting air to the coking chamber and adjustable means for admitting air to the said combustion space.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
